 CPU temp showing as zero

 
 by BubuFearn on: May 11 2014
 
Score 50%

Really love the look of this plasmoid on my desktop just 1 thing doesn't work, CPU temp shows 0 degrees.

I think its grabbing the temp from a wrong sensor that isn't used on my board (PCI 0 I think).

I think the code is doing something like:

sensors | grep temp

And gets back:

temp1: +0.0°C (high = +70.0°C)

which is obviously a sensor that is not used.


If I do:

sensors | grep 'CPU Temperature'

I get:

CPU Temperature: +32.0°C (high = +60.0°C, crit = +95.0°C)

Is there something I need to modify in main.qml to get this working on my boxen?

Hi

This plasmoid uses the systeminfo datasrouce from kde plasma engines, then in most cases, lmsensors not use the same name for core temp in datasource.

For testing, you can play with main.qml, specifically in lines 146 and 147.

https://github.com/dhabyx/plasma-simpleMonitor/blob/master/contents/code/main.qml#L146

In your distro, you can install plasmate package, who contains plasmaengineexplorer app. With this app you can explore the systemmonitor engine, and then change to proper lmsensor datasource.

If you found proper name for your sensor, you can send me the name, and then I would add this to plasmoid.

Regards.

Thank you so much for coming back to me so quickly!

I installed Plasmate as you suggested (excellent tool) and I think I've found the entries you were talking about.

Have taken a screenshot.

http://i57.tinypic.com/sqo6yw.png

I think line 147 is pulling the temprature data from:

lmsensors/k10temp-pci-00c3/temp1

And I think the sensor it should be is called:

lmsensors/atk0110-acpi-0/CPU_Temperature

I'm not really confident enough to edit the code myself yet, as I'm not familiar with the syntax and escape chars.

On a side note..
I did notice some really tasty sensors in there such as lmsensors/atk0110-acpi-0/CPU_Fan_Speed which would be really handy!

How difficult would it be to add some custom sensors to the list such as fan speeds etc? I assume I'd need to create the sensor in main.qml and then reference it somewhere in a UI file?

Hi,

Fan speed not working on any PC. In my PCs this sensors not are available, and then I could not test these sensors.

About your CPU, for testing, you can edit and write the complete name of your sensor without escape characters.

Hi dhabyx!

Please excuse the wall of text, but I've been really busy with your code and wanted to give you some feedback on how I'm doing.

I managed to modify your code to get it to work for my use case, but ended up introducing a weird bug I think is caused by either/both coreTempModel and monitorActions not liking something I've done...

Some background on my use case.

Processor is an AMD Phenom II x6
Motherboard is an ASUS M5A78L-M

The processor has one sensor (k10temp-pci-00c3 temp1) for all 6 cores but it is not a "true" temperature...
As an example right now my motherboard temperature is 30c and yet k10temp reads only 24.5c (note that its a float)

This is because k10temp is a "relative" to "max" temperature used by AMD to tell the processor when to apply extra cooling and not as a reliable guide as to what the "actual" core temperature is.

There are two solutions to this problem:

You could write a formula to convert the relative temperature into an actual core temperature, but the problem with this is that as the temperature changes (and gets lower) the formula you use becomes more inaccurate because its an arbitrary scale and not an actual temperature reading.

The second solution seems to me to be the most sensible for my use case and that is to simply use the motherboards sensors chip which gives us an accurate enough CPU temperature with the added bonus of a few other sensors such as CPU and chasis speeds as well as some voltage stats.

Using plasmaengine explorer I've been able to connect to these sensors and pull data from them.

$ sensors
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.34 V (min = +0.80 V, max = +1.60 V)
+3.3V Voltage: +3.27 V (min = +2.97 V, max = +3.63 V)
+5V Voltage: +5.01 V (min = +4.50 V, max = +5.50 V)
+12V Voltage: +12.11 V (min = +10.20 V, max = +13.80 V)
CPU Fan Speed: 1638 RPM (min = 600 RPM, max = 7200 RPM)
Chassis Fan Speed: 1896 RPM (min = 600 RPM, max = 7200 RPM)
CPU Temperature: +41.0°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +30.0°C (high = +45.0°C, crit = +75.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1: +24.5°C (high = +70.0°C)
(crit = +83.5°C, hyst = +78.5°C)

As you can see k10temp has weird readings, the high crit and hyst are basicaly thresholds that temp1 uses to control fanspeed, and temp1 itself is of no real value to us as an actual reading of true temperature.

The motherboard's sensors (atk0110-acpi-0) seesm much more useful to us and that's what I successfully changed in the code, replacing the original k10temp lines with the new sensors on atk0110-acpi-0.

I also had to change text: 'Core '+model.index+':' to text: 'CPU Temp:' in CoreTempList because I don't have a per core sensor. Somehow this has caused CpuWidget to freak out here:

plasma-simpleMonitor/contents/code/monitorWidgets/CpuWidget.qml:20: Unable to assign QObject* to QDeclarativeComponent*

I think this has caused some issues, I've had a problem with the logo changing back to Tux after logout even when the changes are applied and saved, after logout for some reason it won't apply changes. (Possibly I didn't package the plugin correctly before installing it)

Although the CPU Temp is now correct, when I tried to add an extra sensor (a Motherboard Temp using a modifed coreTempModel I had issues anchoring it nicely below CPU Temp, I suspect this is because I have invisible coreTemps being generated by coreTempModel and generating white space.

I've created a fork on github so you can have a look at the mess I made of your code :P
I have a good idea of what I want to achieve but my JavaScript knowledge is letting me down, so please forget any obvious code mistakes.

I posted a picture of my desktop here:

http://i58.tinypic.com/2vj7477.jpg

If you look closely you can see where I modified coreTemp slightly.

What I'd really like to do is put some of the other sensors I found below "CPU Temp", because as you can see it looks a bit lonely on the left there.

Anyway check out my fork and let me know if it would be too much hassel to customise it.

Hi!

I only started using Git a few days ago and somehow lost the comments you made after viewing them once. I have no idea how to get them back. Or how to reply to them if I did, so please accept my appologies for replying here rather than directly on Github. I am working hard to imprpve.

In answer to your question on the akt0110-acpi-0 sensors.
Yes there is only a 0 there is no 1,2 or 3.

The problm is that whilst ASUS is a very popular board for AMD processors there maybe other users with different boards.

If that becomes a headache for you to support, I completely understand and would have no problem maintaining my own custom version.

Of course if you can include my use case into the main code without too many problems that would be fantastic!

I don't know if you have a Bitcoin/Litecoin/Dogecoin/Paypal address, but if you do I'd like to make a small donation as way of thanks for all your hard work so far.

Hi!,

If you can test the latest version of plasmoid, you can see experimental support for atk sensors instead o k# series.

Give me a feedback if this changes work fine with your sensors, you can write here, in github or send me a private message.

For donations you can send me an private message :)

Any chance we could get an option for Fahrenheit? Seeing my temperatures in Celsius doesn't really mean much to me...

Thanks! I investigated the code a little and it seems that you're using lm-sensors so all you need to do is add the "-f" flag to sensors.

From what I can see, the code doesn't pipe the command to lmsensors it pulls it from a plasma data engine source, so I imagine he will need to do the conversion on the fly or possibly modify the datasource, which I imagine would be more dificult.
It is probably lmsensors doing a conversion on the fly that gives you degrees F.
If you install plasmate and run plasmaengineexplorer you'll be able to see what he has to work with :)
Having said that I know with Python we can pipe commands to a terminal by calling 'popen' and then use regular expressions to find any data we want.
I'm not sure if this is possible with JavaScript?

In QML it's not possible run an application, only in QML for Qt5 it's possible.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
